Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Nikon L31 and Nikon L24 side-by-side from the front, back and top in their relative dimensions. Nikon L31 has external dimensions of 96 x 59 x 29 mm (3.78 x 2.32 x 1.14″) and weighs 160 g (0.35 lb / 5.64 oz) (including batteries). Nikon L24 has external dimensions of 98 x 61 x 28 mm (3.86 x 2.4 x 1.1″) and weighs 182 g (0.40 lb / 6.42 oz) (including batteries).
Below you can see the front view size comparison of Nikon L31 and Nikon L24. Nikon L31 is 2mm narrower and 2mm shorter than Nikon L24 but it is also 1mm thicker.
Here is the back view size comparison of Nikon L31 and Nikon L24.
Now lets look at the top view comparison of Nikon L31 and Nikon L24.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon L31 is 22g lighter than the Nikon L24 but we don't think this will make a significant difference.
Unfortunately neither Nikon Coolpix L31 nor Nikon Coolpix L24 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
LCD Screen Size and Features
Nikon L24's 3" LCD screen is slightly larger than Nikon L31's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
